I am using corridors to model a driving course. I have attached two images that show 2 scenarios. One is where an alignment loops back onto itself. The other is similar to a merging lane.
What are the best ways to handle these? I am having a hard time with the surfaces overlapping. I have tried using targets, but they don't work well.
How do I merge 2 corridor surfaces that are running parallel to each other. Due to this being an overlay project the CL will stay the same just raised 4.5" from existing CL and the existing cross slope varies which we are matching until you hit the sawcut. We are not ripping out or milling any apshalt, it is strictly an overlay of the exisitng with 4.5" of new asphalt. We are saw cutting 2' either side of theedge of paveement and matching in with proposed.
I have created a feature line over the existing cl then raised it the required height. the cl has been offset 10 both sides to create my left and right shoulder alignments, I then created a left and right shoulder corridor assembly which has supplied 2 seperate surfaces. I now would like to merge the 2 surfaces using the raised cl feature line as a break line to create the final proposed surface. I would prefer not to have to create feature lines from my corridor and create a new surface because i would like to take asphalt and subgrade quantaties at the end with out having to hand calc but will if need be.
I've read that it is possible to "hand draft" small complex areas that a corridor cannot handle easily.
I have an intersection in an old neighborhood that is constrained by retaining walls, buildings, and so on. In this I have to fit in current ADA ramps. Due to constrained space I will have to get creative in my elevations and layouts.I'd like to somehow integrate it with the corridor.
I have created a surface from a corridor. I set the boundary of the surface to the daylight of the corridor. In some areas of the corridor the surface does not triangulate see attached.
Copy a corridor successfully? I'd like to try this just a little worried about the explosion of evil this may cause to my Civil 3D session.
Even all the properties of the corridor setup from one to another would be useful. I'm building one corridor and an 2nd one that matches everything except I need to replace my Assembly with one meant for stripping.
My corridor surface is not matching my corridor top links. see attachments. this is affecting my volumes!
The section-plan(surface red).png is showing the section editor and the plan view. the red highlighted line in section is the corridor surface and as you can see in plan view the surface is incorrect and wiggly.
The pdf is all my sections with the red linework being the corridor surface.
I am tring to grade a complex object. Please see the attached document. The two grading objects are not interfacing correctly when graded although i can get the surface almost correct i beleive. Is there a way to remove this issue or the grading will not create a lot of difference when computing the volume clacs ( we are talking volum computation roughly about a million cubic metres cutting).
Sometimes when I select a polyline with many vertices (extracted contour line) Civil 3D 2011 almost stops working. I have tried locking the layer, but this still slow to a crawl.

I used to be able to hatch most anything without problem. Now with Civil 3d 2011 anything more complex that a box or a circle AutoCAD will not find the boundary even when the quick preview seems to find a boundary.
I've tried overlapping the lines and then trimming. I've tried extending to the other lines. I've tried setting the tolerance to 1/2". I've checked that the lines are snapped to endpoints and meet cleanly.
In testing I've found that sometimes it will find the boundary, and other times it will not even when nothing has changed? Noticing that they have to try multiple times and methods to get C3D 2011 to hatch correctly?
The attached file shows the different results (boundaries extracted from successful hatches) that I'm seeing, and sometimes can't find a boundary at all, sometimes it does. Seems to get different results when I regent and at different zooms (not sure if that's the correct terminology?).
I'm currently trying to model all siteworks for a project using Civil 3D 2014. I created several grading groups that represent the various pads I need for the general project layout. Since this was the way I knew how to model the pads, now I have some intersections on the slopes between one grading group and the other. I was wondering if I could "merge" the grading groups in order for them to be just one big pad, that maintains all the levels from the other pads. Here is an image of what I am trying to explain:
What I want to do is to merge the regions circled in red, so that I have only one building pad on my terrain.
I'm in the deployment testing phase of rolling out Civil 3D 2013. We're currently using Civil 3D 2011. We've done a moderate amount of customizing to 2011 to make it work for us - mainly in styles, but we did add a special pipe library because we still run into jobs that use clay pipe and other "non-standard"/"non-modern" items.
The problem is that we don't want to have redo the work to use our custom pipe libraries. At the same time, we want to use anything that Civil 3D 2013 starts us with in the "Imperial" configuration because we've not completed our customizations and there are new things that our default starting drawing doesn't know about (pressure pipes and railways come to mind).
So I'm wondering what the best method of merging the two libraries is. Can I simply look for files that are only in our 2011 pipe library folders and copy those forward?
It may stop us from creating pipes and parts in the future, because I for one do not relish the idea of recrating things everytime an upgrade happens.
As you can see in my attachment, I have a emergency spillway coming out of a dugout wetland. The fill area, the pool area, and the emergency spillway channel are all separate surfaces. All three of these surfaces are created from gradings. The fill was a feature line drawn around the top witdth of the dam, and then graded down to the Existing Ground. The channel is another polygon feature line with elevations at each PI and then graded up to the EG. The pool was a feature line I drew around the perimeter of my pool, laid on the surface EG, and then graded down to an elevation on a slope.
I'd really like to blend all the surfaces together. Right now, they are all separated with tiny slivers of Existing Ground.
How do I go about this? As you can see, I'm still pretty green with gradings.
when I created a Top surface, C3D showed me otherwise. I need a gap at an intersection. In the attached DWG the intersection corridor has been removed from view by isolate.
I used 2 seperate baselines to force the road corridor to have a gap at the intersection.
Looked OK .. except ..later .. when I created a Top surface, only the first baseline is used to create the surface, the second baseline is skipped : (
I obviously did not make a gap correctly. What is the correct way? Or.. is there no way .. must the designer create multiple seperate corridors when the road has gaps?
When pushing F1 for help in 2012 Civil 3D regarding this feature, it takes me to a page about migrating custom files over.
It says to copy the pipe/structure files over, then to open up Civil 3D and type in PIPECATALOGREGEN. Well, it doesn't work and says that it is an unknown command.
I have a very basic question about creating corridors. As you can see on the attachment, i created an assembly consisting of ditch and my own polyline subassembly and turned it into a corridor. The ditch part is drawn out correctly, but the other part (supposed to be a gravel road) has only sections in certain points.
I started playing around with 3d dwf's. I'd like to share my corridors in a 3d dwf viewer or something similar but when it opens in design review, everything is skewed/ jagged/garbled. The other problem is that it exports everything (assemblies, alignments, sections etc.) so it make viewing navigation difficult in the viewer for people that aren't CAD savvy to begin with. It would be ideal if you could select what you want to export similar to exporting a wmf file.
How do others share 3d models with non-cad people?
We are trying to edit a small portion of an existing corridor by adding a generic daylighting subassembly. The add subassembly tool in the Corridor Section editor works, but we get an error because the new sub doesn't have a target surface specified. how to add a target for a sub that is added after the corridor was created?

When creating an alignment from corridor feature (ditch invert level), the created alignment is not following the selected line (see image bellow). The alignment seams to be created from the first point of the feature line to the last point and ignores all the other points. The vertical alignment created at the same time seams to be correct.
I am trying desperately to create a corridor in C3D 2013.
I have the requisite Alignment, Profile and Assembly, yet when I create the corridor, either nothing appears, or it creates the corridor at incorrect elevations. I have the proper elevations in my alignment.
I had a grading plan all set, with a corridor involved. Then, I received a new survey that I didn't know was coming. I need to move all of my elements to different coordinates. I can move everything except the corridor.
I only get 2 choices when selecting corridor feature line to create profile - ETW_base, and ETW_sub. My Subassembly has 2 pavement sections, a base and subbase section. I need the top of pavement profile.
I started with a points file which I created an existing surface called EG. I then used a number of feature line to create the gradings, grading surfaces and associated volume surfaces (compared to EG) also had other drawing elements and aerial photo in place. I had a lot of grading scenarios to do and it was all in one file. It was getting out of hand, so I duplicated the file, deleted the gradings (retained the EG surface) then added another set of new gradings and volume surfaces against EG. I did this in 4 files. So now I have multiple files that contain duplicates of the same EG surface and other features, but have unique gradings and surfaces referenced to those individual EGs.
Files all have similar structure:
+Various features (duplicated in all files)
- base aerial photo
- other drawing elements
+Surfaces
- EG surface (duplicated in all files)
- Grading A-1 surface
- Grading A-2 surface
- Grading A-1 volume surface
- Grading A-2 volume surface
+Site A
- Grading A-1
- Grading A-2
I recognise now that I should have data shared the EG surface from 1 file (and xrefed the other common drawing elements??) but given my situation now, what is the recommend way of putting it all together?
I am trying yo model river corridor with 4 locks on it. On every locks different between levels is about 2-3m. I it is possible to create profile perependicular to bottom of river. How to create it?
Another question how to later connect surface. I mean Existing ground and corridor intersect. Ho to prepare later for render Existing ground with cutted corridor river? where I am below EG.
I have sevreal corridors with various spurs. The contractor wants the cut/fill volume in sections along the corridors, not one big cut/fill calc. Is there a way to do this in C3D? I have got the volume table with the chainages on, but he does not want a cumulitive figure for the whole corridor.
I am trying to create a surface from a corridor. I have a sub-assembly attached, which I believe is working correctly. I managed to create the empty surface and when I try to add surface data nothing seems to happen. I keep changing the specified code to Base which is my finished gravel structure and hit the + but again nothing seems to happen.
Ultimately I am trying to determine a volume between my corridor and original topo.
